Eric Mun’s style of being a leader (if you watch Shinhwa’s 18th in VLive+ -cooking part- you will notice it)
He hears all of the opinions first
Correct them if they wrong in a very casual way
Add something that maybe important but unthinkable for other members
Watch closely of all the process
Completely trust the members
Help the other here an there
Make sure about timing and precision
…
…
Appreciate, give the credit to the one that did the work
…
…
Take all of the responsibility if something happen beyond the expectation
…
…
He has been doing all this stuff for 20 years… the members know, how to do their best to complete their part to please him, because if something happen, they completely sure that the leader will have their back and take the responsibility part for them.
